SPECIFILATION forming part of Letters Patent No. 654,800, dated July 31,1900. Application filed March 25, 1899. Serial No. 710,424. (No model.)

To GJZZ whom it may concern:

Be it known that WBJWINFIELD S. LIVEN- GOOD and GABRIEL LIVENGOOD,citizens of the United States, residing at Kansas City, in the county ofVVyandotte, in the State of Kansas, have invented certain'new and usefulImprovements-in Baling-Presses,of which the following is a full, clear,and exact description, reference being had to the accompanying drawings,which are made a part of this specification.

Our invention relates to improvements in baling-presses, having moreparticular refer-- ence to improvements in the power end of the pressand the, devices and arrangement of devices by which the pitman isoperated and controlled; and our invention consists in certain featuresof novelty hereinafter described, and pointed out in the claims.

Figure I represents a plan view of the pitman of a baling-press and itsimmediate op-- erating and controlling mechanism embodying ourinvention, this view showing the pitman and the positionfand operativerelation of the parts at thebeginning of the instroke of the pitman.Figj II represents a plan view showing the pitman and operative relationof the parts at the end of the instroke of the pitman. Fig. I IIIrepresents a plan view showing the pitman and the operative relation ofthe parts at that point in the cycle at which the tr'ip-arinpasses toand-takes efiect upon the end of the pitman. Fig. IV represents a sideelevation of the same, showing the pitman and operative relation of theparts as shown in plan view in Fig. II.

Similar numerals refer to similar parts throughout the several views.

1 represents the axle upon which the power is mounted.

2 represents the power-shaft, mounted in a foot-step carried on the axlein the usual manner. 7 3 represents a hub fixed upon and arranged toturn with the power-shaft. Upon said hub are provided the series oftrip-arms 4, 4 and 4:", having the usual antifriction end rollers 5. The.yoke and horse lever or sweep by which the power-shaft is operated,being of the usual construction familiar in the art, are not shown.

6 represents the pitman, having aconvex inner face 7 and a square end7,with our pit man-controlling device, the concavity form'- ing a pocketin the pitman end usually provided not being required.

8 represents a guide-lever pivotally mounted on a stud 9 on'thebed-plate 10.

11 represents a link connecting the arm 12 of said guide-lever with thepitman, the pitman end of said linkoperating in the slot 13 in thepitman-head. On the other end of said lever is formed the block 14,which at the proper time operates as a stop-block to determine the sidemovement of the pitman and prevent its passing the center at the end ofthe instroke.

15 represents an eye formed on the guidelever, to which one end of thecoiled spring 16 may be connected, the other end of said spring beingconnected with the pitman in the usual manner, said spring serving thepurpose'common theretoof retracting the pitman when the pressure injtliebaling-cham her is not suificient to cause the rebound.

In operation, as shown a in Fig. I, at the beginning of the instroke thelever-arm 12 is in the path of the trip-arm 4 while the next succeedingtrip-arm 4E bears against the inner side of the pitman-just to the rearof the con-' vex; face or hurnp thereon. Then as the trip-arms advancein their revolutions the arm 4*, acting upon the lever-arm and throughthe link 11 upon the pitman, tends to draw the pitman sidewise or-towardthe powershaft; but this being prevented by the action of the arm 4 theresult is that the pitman is drawn backward, not, however, in a straightline, but on a compound curve formed by the action of the link as aradius with a mov ing center, the action of the trip-arm 4 tendingconstantly to carry it off of the curve on the link, and the action ofthe hump 7 on the pitman tending to still further modify the curve, thelink and guide-lever, however, constantly controlling the path of thepitman. During this part of the movement, the trip-arm 4* acting uponthe lever-arm and through the link upon the pitman to draw the pitmanbackward, the backward movement of the pitman is very rapid, much moreso than if the end of the link were fixed instead of moving and thebackward move ment of the pitman were due to the action 2 e54,eoo

of the trip-arm 4 alone. It also moves through a larger space for-agiven movement of the trip-arm 4 than would be possible if the pitmanwere given its impulse solely by the trip-arm 4. The extent of thisaccelerated movement of the pitman is seen by comparing Fig. I with Fig.III, from which it will be seen that from the beginning of theinstroketo the point at which the trip-arm roll' passes to and acts upon the endof the pitman, while the trip-arm has moved through but about one-thirdor less of its course necessary to the full stroke of the pitman, thepitman itself has moved through nearly twothirds of its stroke. "Thisaction is of the greatest advantage and importance, for during this partof the travel of the pitman the hay in the baling-chamber being in aloose condition but small amount of power is required to press it. It istherefore desirable that the travel to bring the trip-arm to bear uponthe end of the pitman should be made as quickly and with as littletravel of the team as possible. At the end of the'instroke, as thepitman is released from the trip-arm and under pressure of the hayrebounds, the

- path of the pitman on its rebound is deterimined and controlled by theguide-lever and ink.

By the use of three trip-arms on the hub the pitman is given threestrokes for each revolution of the power-shaft or with each round of theteam. In this there is not only a gain in time, as is manifest, but thepitman acting more quickly and more frequently smaller bunches of haymay be fed into the feedopening, thus insuring more rapid and evenAnother adand arrangement embodying our invention Weare able tomake theradius of the triparms shorter by about one-fourth than in any trippingdevice now in use, and in consequence can use a horse lever or sweepshorter in like proportion, and thus with the team walking at the samerate on a smaller circle will gain largely in the dailycapacity of thepress. We would not, however, limit our trip to three arms, as it ismanifest that our pitman-controlling device with some purely mechanicalchanges in construction could be operated with two or with more thanthree trip-arms. We are also aware that a tripping device giving threestrokes of the pitman to each revolution of the power-shaft has beenused on a baling-press, but we are not aware that such device has beenbefore applied where a long stroke is given to the pitman, having beenlimited to take effect immediately and directly upon the end of thepitman.

Having thus fully described our improvements, what we claim as ourinvention, and desire to secure by Letters Patent, is-

1. In a baling-press having a suitable bedplate the combination with thepower-shaft provided with three trip-arms having antifriction-rollers intheir ends, of a pitman, a guide-lever fulcrumed on the bed-plate to therear of said power-shaft and arranged to operate in the path of saidpower-arms, and a link connected with said lever, and with the pitmancontrolling the path of the pitman, substantially as set forth.

2. In a baling-press having a suitable bedplate, the combination with apower-shaft pro- Vided with triple power-arms having antifriction-rollers in their ends, of a pitman having a convex inner face,a guide-lever fulcrumed on the bed-plate to the rear of saidpower-shaft, and arranged to be operated by said power-arms, and a linkconnected with said lever and with the pitman and arranged to controlthe path of the pitman from the beginning to the end of its cycle;substantially as set forth.

3. In a baling-press having a suitable bedplate and a verticalpower-shaft mounted on said bed-plate, the combination with a pitmanhaving a vibrating end portion, of a triplearmed trip-lever mounted onsaid power-shaft and arranged to operate the pitman, a lever fulcrumedupon the bedplate and arranged to be acted upon by said power arms andto act upon the pitman to give an accelerated initial movement to thepitman, and means for retaining the pitman within theaction of saidpower-arms whereby said arms act first upon the side and then'upon theend of the pitman; substantially as set forth.
